Glad you enjoyed it! Yeah, aiming does seem like it could be challenging. I suppose when I have been making the game for a week, I kind of just learn where each one ends up firing.
If we do end up expanding upon the game, then one possible option could definitely be a laser pointer addon to guns.
Only being able to use a third of them is definitely fair, but to be honest I'm not really sure how I could improve upon that.
Thank you for all the feedback, it is all very much appreciated!
